When Oprah Winfrey‘s longtime publicist Lisa Halliday quit this week, sources assumed the two women had a falling-out. Halliday is leaving after 12 years with Harpo to move to LA. Sources told us that Winfrey wanted her to stay put in Chicago, where she would work with Rosie O’Donnell‘s new talk show on OWN.
